Zradix, I've had that same experience a time or two, and I know how you feel. I'm happy for you. I'm not a natural talent either, so these moments for me aren't a regular thing. I do love it when it happens though. Not sure what causes us to "get in the zone", but it sure is fun. I've had similar experiences playing basketball and golf.
The longer I'm at it, the more that I think for me it has to do with good visualization. When I'm shooting lights out I seem to see the shots before they happen. Trouble is, it doesn't seem to be something that I can force myself to do. At least, not consistently.
Wish I could offer some insight on getting it to happen more often!
